You can isolate y and you know that the slope is the number in front of x (the one that multiplies it)
You know that the y-intercept is the value of y when x=0, therefore you can find y by replacing x with 0 in the equation
1-equation
5x-8y=3
5x=3+8y
5x-3=8y
(5x-3)/8=y
y=(5/8)x -3/8
(Slope = 5/8)
2- y-intecept (x=0)
y=(5/8)(0)-3/8
y=-3/8
Use the formula,
I = Prt
P = Principal amount = 400
I = interest = 18
r = annual rate
t = time in years = 9/12 = 3/4
so,
18 = 400*r*3/4
r = 0.06
so the annual interest rate is 0.06 or 6%.
Answer:
GURL MY MATH TEACHER GAVE ME THE SAME SHEET A MONTH AGOO
YASS
1.) x is less than or equal to 3
2.) x greater than or equal to 2
3.) x < -1
4.) x greater than or equal to 3
5.) x>2
6.) x greater than or equal to 1
3 plus 5 plus 2 is 10 because if you add 3 plus 5, it equals to 8 and 8+2 equals to 10.
